Solved: "Cannot connect to primary DNS Server" (problem not solved like i said before)

EDIT: ok i thought i fixed the problem, but i actually didn't

So the internet connection on my laptop has always been fine this past month. But in the last couple of days, I couldn't connect to the DSL connection. The internet on the other two computers in my house are working fine. It says I'm connected to local only, but not internet. And when I tried to diagnose the problem, it said "Windows confirmed that this computer cannot connect to Primary DNS Server." I don't have a router. I don't remember doing anything differently in the past couple of days. So please help me!

-My ISP is AT&T Express DSL. United States
-Ok I wasn't sure if this is right, but I went to control panel>Device Manager>Modems and it says HDAUDIO Soft Data Fax Modem with Smart CP
-No router
-Connection - wired connection
-And I don't know if this is the right info either, but in Device Manager, under "Network adapters," it says Broadcom 4321AG 802.11a/b/g/draft-n Wi-Fi Adapter and NVIDIA nForce Networking Controller
-Make Model: Hewlett-Packard, HP Pavilion dv6000
-Windows Vista Home Premium

Ok, so you know how in the tray icon, it displays your internet connection. Like when my ethernet is not plugged in, then there's a red X there. Well now when I let my mouse go over there, it says "Local Only." A few days ago, it always said "Local and Internet." And when I go to Network and Sharing Center, and I click on View Status for the Local Area Connection, it says:

IPv4 Connectivity: Local
IPv6 Connectivity: Limited

I think that has something to do with it? Like IPv6 is internet-related right. And so the speed says 100.0 Mbps, and so it seems like I would have connection, but I don't.

Anyway, So I went to Network and Sharing center, and went to "Diagnose and Repair" (I was just trying anything I could), and the exact error message says:
"Windows confirmed that this computer cannot connect to "Primary DNS Server"
This server may not be available
->Windows found a problem that cannot be repaired automatically. Contact your Internet service provider or network administrator for help or click her for information about things you can try to help resolve the problem

And I clicked there, but nothing helped. It just talked about stuff like make sure your modem is turned on, and it is. And the ethernet was always plugged in correctly.

And I don't know about contacting my ISP, because again, the internet connection on the other two computers in my house are working just fine. And the connection on mines started acting weird a few days ago. Ahhh so frustrated. But will this Primary DNS server issue interfere with wireless or my future internet connection elsewhere? Sh*t I have to go back to college soon and this is a new laptop.

First, you do have a router. Your router is a 2wire. and if you are xxxing out your IP addresses it is only making it harder for us to tell what is happening!!! The whole point of posting that was for that info!!

Well, you're getting at least as far as your router. Try a couple more pings. All you have to tell us is whether you get 4 Replies or all packets lost. I'm expecting failure since png 4.2.2.2 failed, but please try them anyhow.
